Ton/,ZZ whom' t may concern:

Be it known that I, LESLIE VGini-Nn, a citi-kV zen Voifcthe United.V States,A Vresiding at Rutland, in the county'of Rutlandvand State of Vermont, have invented certain i new and useful Improvements in Sway-Bar Bearings :tor Gang Saws, of which'thefollowing is a specification, referencebeing'had therein to the accompanying drawing.

' This-invention relates to certain new and useful improvements in swaybar bearings for gang saws, the .object being to provide novel means Jfor mounting the Y sway barin respect tothe frame 'of the saw so'thatlthe sway'bar will be supported on theadjustable V.saddle in a bearing whichis thoroughlyv lubricated at all times and "in such a manner vthat the bearing isprotected from the sand; and water used` inthe process-of sawing stone. f f

Another and further object of the inven` tion is to provide a bearing with an oil re'- ceptacle having an adjustableibushing with means `foradjusting the same so as to take up theweanVV f A still further objectv ofthe invention is to vprovide the ends of the sway bar'y with excentric sleeves in order toY allow the oil receptacle to be made smaller by. allowing the sleeves to extend 1down into the oil pocket so as to be thoroughly lubricated at all times.

Other' andlfurther objects and advantages of the invention willvbe hereinafter set forth and the novel features thereof defined in the appended claims.

l In thedrawings,

Figure 1 is a vertical section through my improved construction of bearing showing the same in position on the guide way of the sawing machine; l

Figure 2 is a section taken lon line 2-2 or" Figure 1;

Figure 3 is a perspective view of the ex` centric sleeve;

Figure 4 a perspective view of theusplit bushing; l

Figure 51s a detail perspective view of a rslightlymodiied form showing a concentric sleeve arranged on the sway bar; and

Figure 6 is a perspective view` of a sway ybar showing the same notched in order to' yallow itto drop down into Lthe oil pocket. In the drawing lindicates the corner post of an ordinaryconstructionof sawing ma.-

chine now iniuseto which isl'connecteda guide 2rby bolts as clearly shown, said guide having a saddle 3 Slidably'mounted thereon i passes anadjusting screwgy.

The Vsaddle yyis `provided with a hollow enlargement 6 in which is arranged asplit bushing 7 having a curved upper portion to which is connectednut 4; through which anda three-sided lower kportion lfitting withr` in the hollow enlargement insuch a'manne'ry that it is prevented from turning therein;

The enlargement is Vprovided with an7oil chamber S havinga drain'plug 9-which is l adaptedrto be filled with lubricant and nia-in` i tainedat the oil level as shown by dotted and dash lines and it will be seen that the oil level extends above the *bushing and the bushing is provided with an opening or duct iny order to allow theoil topass into v same in order to thoroughly lubricate the bearing sleeve as will` be hereinafter fully described i i Y f .The inner side of theenlargementis i vided with an opening through. which is adapted toy extendthe'sway bar 11 ytowhich y is Vsecured clamping lugs 1 12 carrying sus-` jack y on the sawjframein theV usual manner. The sway bar -11 isprovided with a 'thrust The inner endV ofthe sway bar 11 re-y clearly shown.

ducedas shown at'14 andkeyed thereonis an excentricsleevel which fits snugly withe0 pension bar 13 .which is connectedto the4 in the split brass bushing?r so as topform a bearingin which said sleeverocks audit will benoted that by arranging an excentric sleeve on the end of the reduced end of the. sway bar, the sleevey extends down below the oil level soY ythatit will be lubricated.V

which allows the sway bar to be maintained close to the guide. This Yconstruction also Y f enables they pocket Orbearing formed by the :i

enlargement to be maintained within areaksonable size.

` The hollow enlargement is enclosed by a ycap 16 secured in position thereon 'by bolts 20 are bolts 21 which are adapte-d to engage the split'bushingy and hold the same tightly against the sleeve carriedvby the sway'bar ico f ics Y said cover for adjustingV and it will bekseen that as thebushing and sleeve'we'ar, `the bushing can be adjusted so as-to take up all lost motion',l the bolts 21 being locked in positionby set nuts 22.

In Figure 5 I show a sway bar 25 provided with a concentric sleeve 26 in order to Vallow the 'sleeve to fdrop in the oil pocket so as to be thoroughly lubricated.

In Figure 6 I show a sway bar 2T notched at 28 in order to allow the same to drop into the oil pocket.

. From the foregoing description it will be seen that I'have provided a vnovel form or sway bar ymounting inthe forni ora bear` ing formed' on thev saddle having a pocket forming an oil chamber iii which is yarranged an adjustable bushing forming a bearing `for an excentric sleeve keyed on the reduced end of asway bar in such -a manner that the sway bar is mounted close to th'e guide. What I claim is l. A sway bar bearing for Vgang saws comprising'a chamber having an irregular shaped bushing mounted therein provided with an oil pocket, a sway bar having an excentric lsleeve mounted in said bushingV arcover for. said chamber vand adjusting bolts mounted 'in said vcover adapted to engage said bushing.

Y' 2. The combination with a stone sawing machine having a Saddle, o-a chamber formed on said saddle having a removable cover, a split bushingy mounted within said chamber, a sway having a reduced end carrying an excentric sleeve mounted in said bushing and bolts adjustably mounted in said split bushing around said sleeve. Y

A saddle for gang low enlargement to form an oil chamber, a non-rotatable split bushing mounted in said chamber, a sway bar having areduced end carrying an excentric sleeve mounted in said bushing, said bushing being provided with an oil duct in communication with said chamber and a cover for enclosingsaid chamber having screws for engagingsaid saws having a hol' bushing for adjusting said bushing around said sleeve. l

v t. In a stone sawing machine, the combination with al saddle having an enlargeinent to provide a chamber adapted to containr lubricant, a non-rotatable bushing mounted in said chamber having an oil duct, ksaid chamber being provided with an opening inone side wall, a sway bar extending through said opening having areduced end,

' 6. A sway bar bearing for gang saws comprising a chamber having a non-rotatable split bushing Vmounted therein. a sway .bar carrying an eXcentric sleeve mounted within said `bushing and avcover for closing .said chamber having aset screw for adjusts ing said bushing around said sleeve.A

7. A saddle for gang saws having a hollow enlargement Ato form an oill chamber having a drain plug, a split bushing having fiat faces arranged withinsaid chamber and provided with an oil duct, one wall of'said chamber being provided with kan opening, a sway bar extending through said opening, an excentric sleeve keyed on said sway bar mounted within said bushing, a coverfor closing said chamber, a Ynut arranged in said lcover and a screw working in said nut adapted to engage said bushing for adjusting saidbushii'ig around said sleeve.

In testimony whereof I hereunto afix my signature. f
